Boston MA, 1967, Tri-X

Olympus XA 35mm lens XP2

I have had quite a lot of experience of this issue over the last few years. Here's a summary: 1. My Nikon F (about 1969) with a FTn meter head - it takes 2 x 1.35V PX625 (in the meter head). When I had it serviced by a classic Nikon specialist technician recently, he adjusted / calibrated the meter so it could work with modern 1.5V PX625s. 2. My Canon EF (1976) - see above - I use the 1.35V zinc-airs or modern 1.5V PX625's. 3. My Canon F1 (1975) does not have the voltage regulator. The battery just powers the meter as the camera is mechanical. I use the zinc-air 1.35v cells. There are several companies around, like Polar Bear Cameras, selling the LR44 sized 1.35v zinc airs and PX625 adaptors. The zinc-airs give stable output of 1.35v once activated and usually last for a about a year or more and are cheap enough these days (about €12 / £10 for 5 batteries and an adaptor set). Some other companies selling the LR44 / G10 type zinc-airs at 1.4 to 1.45v as 'hearing aid batteries' don't always give a stable output though with 50 year old cameras with old metering circuits, +/- 0.25 volts in unlikely to be a problem but voltage instability is not good for metering accuracy. I have a hand held meter anyway as a check. NB I guess like many of us, I use the cameras as much as I can but with about 20+ 35mm classic cameras in my collection (Canon, Nikon, Contax), the number if films that go through each body might be just 1-2 per year, so I always remove batteries when the cameras are not being used to prevent leakage issues. I have a spreadsheet where I keep a record of when batteries where changed and if in doubt, I recycle the batteries and fit fresh ones. I keep a good stock of batteries in the refrigerator! Gary

Yes, it does. So you can use Zinc-air 1.35v substitutes or the ‘modern’ 1.5v silver oxide PX625 clones. Either will work with no issues.

You are invited to upload one or more of your landscape photos and, if you’d like, to accompany your image with some commentary: challenges you faced in making the image? your intent for the image? settings? post-processing decisions? why you did what you did? the place and time? or an aspect you’d like feedback on? And please feel free to ask questions of others who have posted images or to join the discussion. If you don’t feel like using words, that’s OK too—unaccompanied images (or unaccompanied words, for that matter) are also very much welcomed. As for the technicalities, the usual forum guidelines apply: files < 1 MB; image size <1000 px maximum dimension. I just can't stay away from the dunes. There's always something new going on.

I thought the EF had a voltage regulation circuit enabling it to use modern 1.5v button-cell battery without worry. Maybe someone can confirm that for me.
